使用Swiftui中的列表以及数据删除对象

Question

我正在尝试找出从list中删除项目的方法，swiftui。我尝试使用.ondlete方法，该方法从数组中删除了条目，但是我不确定如何看到项目的元数据（即对象ID或内容）并使用该条件来从后端删除项目。

        List {
            ForEach(userPostsVM.posts) {
                post in
                FeedViewCell(post: post, isUserPostsView: true)
                    .onAppear{
                        userPostsVM.fetchMoreDataIfNeeded(currentItem: post)
                    }
                
            }.onDelete { indexSet in
                /*this remove the item from the list,
                  however once refreshed the view item
                 is reloaded because it was refetched
                 from the server and was never deleted
                 in the server
                 */
                userPostsVM.posts.remove(atOffsets: indexSet)
                userPostsVM.deleteUserPost(at: indexSet)
            }
        }

尝试了以下方法，但是帖子ID永远不会与从列表行删除的对象匹配

func deleteUserPost(at offsets : IndexSet) {
    self.posts.remove(atOffsets: offsets)
    offsets.forEach({ index in
        let deletedPostId = self.posts[index].id
        deletePostfromServer(postId: deletedPostId)
    })
}

func deletePostfromServer(postId : String) {
    let query = PFQuery(className: "demoClass")
    query.whereKey("objectId", equalTo: postId)
    query.whereKey("user", equalTo: AuthViewModel.shared.currentUser!)
    query.getFirstObjectInBackground { object, _ in
        if let object = object {
            print("DEBUG:  got the object with id \(object.objectId)")
            // above does not match with the object id deleted from the list, hence never runs
        }
    }
}

我想要获得的所有是对象详细信息，即objectId所示的项目特别是已删除的行。 帖子数组是已发布的属性。

我认为，通过将数组状态与以前的状态进行比较，并获得当前状态中的内容，最后使用该对象从服务器后端删除。

任何帮助都将受到赞赏。
